The general inventive concepts are directed to oil-enhanced polymermodified asphalt adhesive compositions for use in membrane-basedapplications. In some exemplary embodiments, the oil-enhanced polymermodified asphalt adhesive comprises polymer modified asphalt that hasbeen further modified with the addition of an oil, such as vegetableoil, nut oil, or seed oil. In some exemplary embodiments, theoil-enhanced polymer modified asphalt adhesive comprises asphalt thathas been modified with the addition of an oil, such as vegetable oil,nut oil, or seed oil, and then has been further modified with theaddition of a polymer modifier.

Exemplary membrane-based applications include, but are not limited to,roofing applications, road repair and/or paving applications, airbarrier applications, tapes (e.g. for sealing windows or doors, or foruse in gutters or decks); and below grade membranes, such as thoseapplied to foundation walls, tunnels, earth shelters, structuralconcrete decks, plaza decks, parking decks, insulating foams, and aboveor below grade split slab construction. Exemplary membrane-based roofingapplications may include low slope roofing; steep slope roofing; andunderlayment. The underlayment may be reinforced (with a glass orpolyester woven or nonwoven) or non-reinforced, and may have a smooth,granular (such as coal slag, sand, or roofing granules), film (such as apolyolefin or polyester), or woven or nonwoven (such as glass,polyolefin or polyester) surface.

In some exemplary embodiments, the oil-enhanced polymer modified asphaltadhesive is used to produce a membrane. The membrane may comprise asubstrate that is impregnated with, or includes a coating of theoil-enhanced polymer modified asphalt adhesive composition.

In some exemplary embodiments, the oil-enhanced polymer modified asphaltadhesive may comprise one or more polymer modifiers. The polymermodifier may comprise any suitable polymer. In some exemplaryembodiments, the polymer modifier comprises an elastomeric radial orlinear polymer. In some exemplary embodiments, the polymer modifiercomprises a copolymer such as a linear or radial copolymer. In someexemplary embodiments, the polymer modifier comprises one or more ofstyrene-butadiene-styrene (SBS), styrene-butadiene rubber (SBR),styrene-isoprene-styrene (SIS), and thermoplastic polyolefin (TPO). Inother exemplary embodiments, the polymer modifier comprises a linearpolymer or a combination of linear and radial polymers. Examples ofpolymer modifiers are disclosed in U.S. Pat. Nos. 4,738,884 to Algrim etal. and U.S. Pat. No. 3,770,559, to Jackson, the contents of which areincorporated herein by reference in their entirety.

The asphalt used in the present composition may include various types orgrades of asphalt, including flux, paving grade asphalt blends, propanewashed asphalt, oxidized asphalts, and/or blends thereof. Effectiveblends of asphalt or bituminous materials are understood by those ofordinary skill in the art. The asphalt may also include one or morefillers, such as a filler of finely ground inorganic particulate matter,such as ground limestone, dolomite or silica, talc, sand, or calciumcarbonate.

Other materials suitable for use in the asphalt composition includetackifying resins and other types of natural and synthetic rubbermaterials and thermoplastic polymers. Additionally, recycled rooftear-off materials, such as shingles, may be included in the asphaltadhesive. Recycled shingles may be processed in a wide variety ofdifferent ways to allow the material to be used in the adhesive. Forexample, tear off shingles may be processed as described in U.S. PatentApplication No. 2014/0014000, the contents of which are incorporatedherein by reference in its entirety, to be used as filler or an additiveto the asphalt.

In some exemplary embodiments, the asphalt is enhanced with an oil oroil derivative additive, forming an oil-enhanced asphalt composition. Insome exemplary embodiments, the oil may comprise one or more vegetableoils, nut oils, or seed oils, of any variety known and generallyavailable in the art such as, for example, soy oil, canola oil, cornoil, peanut oil, sunflower oil, olive oil, safflower oil, rapeseed oil,or mixtures thereof. In some exemplary embodiments, the oil additive isa soy-based vegetable oil. In some exemplary embodiments, the oil hasbeen modified by hydrogenation or oxidation.

The resulting oil-enhanced polymer modified asphalt adhesive maycomprise about 25 to about 70 weight percent asphalt, about 25 percentto about 60 percent by weight of a filler material, about 1 to about 10weight percent of a polymer modifier, and 1.0 to about 8.0 weightpercent oil or oil derivative additive, based on the total weight of theoil-enhanced polymer modified asphalt adhesive. In some exemplaryembodiments, the oil-enhanced polymer modified asphalt adhesivecomprises about 40 to about 55 weight percent asphalt, about 35 percentto about 50 percent by weight of a filler material, about 2 to about 4weight percent polymer modifier, and about 2.0 to about 4.0 weightpercent oil or oil derivative additive, based on the total weight of theoil-enhanced polymer modified asphalt adhesive.

In some exemplary embodiments, the oil-enhanced polymer modified asphaltmaterial is used in the formation of a membrane or laminate for variousapplications, such as roofing applications, road applications, and thelike. In some exemplary embodiments, the membrane material comprises asubstrate that has been coated and/or impregnated with an oil-enhancedpolymer modified asphalt adhesive composition. Thus, the oil-enhancedpolymer modified asphalt adhesive composition serves as the membranematrix, or substantially continuous phase, in which the substrate islocated for strength purposes, and onto at least one side of which is acoating of the oil-enhanced polymer modified asphalt adhesivecomposition, which serves to enhance the membrane bonding to a desiredsurface. In some exemplary embodiments, the membrane will besufficiently flexible to allow it to be formed into rolls in order toprotect the adhesive layer. To prevent membrane adherence in the rolledform prior to the time of use, the adhesive layer may be covered with asuitable removable or releasable skin, such as in the form of atear-away liner.

Referring now to FIG. 1, some embodiments of the membrane 20 maycomprise a plurality of layers. The layers may include a base releaseliner 33 which may comprise a siliconized polyolefin film. Disposed atopthe base release liner 33 may be a first adhesive layer 22 ofoil-enhanced polymer modified asphalt adhesive as disclosed herein. Areinforcing layer 200 may be disposed atop the first adhesive layer 22.A second adhesive layer 24 may be disposed atop the reinforcing layer200. The second adhesive layer 24 may comprise the same composition asthe first adhesive layer 22 or it may be of a different composition. Thesecond adhesive layer 24 may comprise a polymer modified adhesive or maycomprise an oil-enhanced polymer modified asphalt adhesive as disclosedherein. Disposed atop the second adhesive layer 24 may be a surfacelayer 28. The surface layer 28 may comprise granules, which may comprisegravel, sand, or coal-slag; a film, which may comprise a polyolefin oracrylic; or a fabric, which may be woven or non-woven, and which maycomprise a polyolefin or a polyester

In some exemplary embodiments, the reinforcing layer 200 may be afibrous reinforcement layer, such as chopped strand mats, continuousstrand mats, swirl mats, woven and non-woven fabrics, e.g., wovenrovings, insect screening, scrim and the like. In some exemplaryembodiments, the fibrous materials are glass but they may also beorganic polymeric materials or combinations of glass and organicpolymers. The reinforcing layer 200 may be impregnated with asphalt,with the asphalt being either polymer modified asphalt or oil-enhancedpolymer modified asphalt.

Preparation of membrane 20 may include a carrier layer 32 (FIG. 2) topull the oil-enhanced polymer modified asphalt through the manufacturingprocess. In the case where reinforcing layer 200 is present, thisreinforcing layer 200 may become that carrier, making carrier layer 32optional. As illustrated in FIG. 2, the membrane 20 may be formedexcluding reinforcing layer 200. In that case, a carrier layer 32, suchas release liner 32, may be used as the carrier to pull the oil-enhancedpolymer modified asphalt through the process. In addition, layer 24 maynot be present and the construction simplifies to a 3-layer system.

The carrier layer 22 may take a wide variety of different forms. Thecarrier layer 32 can be any material that removably adheres to theroofing membrane. Examples of acceptable materials for the carrier layer32 include, but are not limited to, plastic materials, such as plasticfilms (i.e. polyolefin film, etc.), coated materials, such as paper,plastic or other material coated with silicone or other releasematerial. The carrier layer 32 prevents the membrane 20 from adhering toitself when arranged in a roll, as described below or when sheets of thegranule coated roofing membrane 20 are stacked. The carrier layer 32 maybe removed by a roof installer so that the bottom surface, or surfaceopposite the coated surface 28 of the membrane 20, will adhere to alow-slope roof deck 18, steep-slope roof, or other base roof material,as shown in FIG. 3.

In some exemplary embodiments, one or more of the first and secondasphalt adhesive layers 22, 24 comprise polymer modified asphalt. Thepolymer modified asphalt may be modified by any suitable polymer. Someexemplary embodiments of the polymer modified asphalt material comprisean elastomeric copolymer such as a block radial copolymer. In someexemplary embodiments, the polymer modified asphalt material comprisesone or more of styrene-butadiene-styrene (SBS), styrene-isoprene-styrene(SIS), and thermoplastic polyolefin (TPO). In other exemplaryembodiments, the polymer modified asphalt may be modified by a linearpolymer or a combination of a linear and radial polymer.

In some exemplary embodiments, the membrane 20 is a water resistantmembrane.

In some exemplary embodiments, the oil-enhanced polymer modified asphaltadhesive composition is used in the formation of a roofing membrane usedin roofing applications, such as low-slope, steep-slope, and flat roofs.As used in this application, the phrase “low-slope roof” is defined as aroof having a slope or pitch less than 4:12. Typical low slope roofshave a slope greater than about ¼:12 and less than 4:12. Proper roofdesign requires some slope to promote drainage and prevent waterponding. As used in this application, the phrase “steep-slope roof” isdefined as a roof having a slope or pitch greater than 4:12. Typicalsteep-slope roofs have a slope or pitch greater than 4:12 and less thanabout 18:12, however, some steep-slope roofs may be even steeper.Details of typical steep-slope roofs can be found in the Asphalt RoofingResidential Manual, 2006, published by The Asphalt Roofing ManufacturersAssociation (ARMA). Unless otherwise indicated, the roofing membranesdescribed herein can be used in any of low-slope, steep-slope, and flatroof applications.

Referring now to FIG. 3, a building structure 10 is shown having a steeproof 11 with a shingle-based roofing system 12. While the buildingstructure 10 illustrated in FIG. 3 is a residential home, it will beunderstood that the building structure 10 may be any type of structure,such as any residential, industrial, or commercial building. In theexemplary embodiment of FIG. 3, a low-slope roof 16 extends from thebuilding structure 10 and may cover an open or enclosed patio, garage,or carport, for example. The low-slope roof 16 includes a low-slope roofdeck 18.

When the membrane 20 is a traditional shingle, a layer of smallparticles, such as sand, is adhered to the first adhesive layer 22. Thisis referred to as backdusting. The backdusting prevents the shingle fromsticking to other shingles when packaged. When the membrane 20 is aself-adhering roof covering, the first adhesive layer 22 adheres thereinforcement layer to the roof or an optional release layer 32 orunderlayment. The surface 28 is adhered to the reinforcement layer 200by the second adhesive layer 24.

The second adhesive layer 24, if present, may be identical to the firstadhesive layer 22 or the adhesive layers may comprise differentcompositions. In some exemplary embodiments, the second adhesive layer24 comprises a core batch layer, comprising unmodified asphalt, and thefirst adhesive layer comprises the oil-enhanced polymer modified asphaltadhesive compositions disclosed herein. In other exemplary embodiments,both the first and second adhesive layers 22, 24 comprise theoil-enhanced polymer modified asphalt adhesive compositions disclosedherein.

The surface coating 28, asphalt adhesive layers 22, 24, reinforcementlayers 200, and/or release/underlayment layers disclosed herein can becombined in a variety of different ways to construct many differentmembranes 20.

The oil-enhanced polymer modified asphalt adhesive disclosed herein maybe produced by any method of forming an asphalt adhesive commonly knownand used in the art. In some exemplary embodiments, the method comprisesheating asphalt in the presence of an oil or oil derivative additive, toproduce a molten oil-enhanced asphalt material. A polymer modifier, asdescribed above, may then be mixed into the molten asphalt material,forming an oil-enhanced polymer modified asphalt adhesive compositioncomprising any of the embodiments described or otherwise suggestedherein.

In other exemplary embodiments, the asphalt may first be modified by apolymer modifier, forming a polymer-modified asphalt. An oil or oilderivative, as described above, may then be mixed into thepolymer-modified asphalt.

In some exemplary embodiments, the oil-enhanced polymer modified asphaltadhesive is prepared by the following method. The necessary amount ofasphalt and oil (amounts vary by type of oil) are mixed together under ahigh shear mixer (an example of which includes a Silverson Lab mixer)over heat. Once a temperature of 320° F. is reached, the polymer isslowly added. The mixture is maintained at a temperature between 350 and385° F. while mixing under the high shear mixer for one hour at 4000RPM. The filler is then added and mixed for an additional 30 minutesunder the high shear mixer and then, finally, mixed by hand using astirring tool. The mixture is then allowed to cool to 310° F. or less.

All combinations of method or process steps as used herein can beperformed in any order, unless otherwise specified or clearly implied tothe contrary by the context in which the referenced combination is made.

In some exemplary embodiments, the oil-enhanced polymer modified asphaltadhesive compositions disclosed herein exhibit improved properties, suchas improved cold adhesion (both long and short term), elongation tobreak, recovery, tensile strength, and/or shelf-life. Elongation is themeasure of ductility of a material and is measured by the ratio ofchange in axial length to the original length of the material. Moreflexible materials have a much higher elongation than that of a rigidmaterial. Ductility is a material's ability to deform under tensilestress and is the maximum stress that a material can withstand whilebeing stretched or pulled before failing or breaking.
